✦ Synopsis

Mn K-edge XAFS together with LEED and thermal desorption has been used to investigate a series of Mn multilayers deposited on a Ru(00 1) substrate under UHV conditions. It is found that a meta-stable phase with a (1 x 1) LEED pattern can be prepared at thin as well as thick layers. The XAFS of such a system appears to exhibit an intense HCP-like EXAFS pattern indicating that the as-deposited Mn overlayer is pseudomorphic with the substrate. Upon annealing, the XAFS of the meta-stable phase collapses to a pattern similar to that of the bulk Mn.
